I understand.

Yes! My laptop video card is even not supported on svgalib 1.9.24. It is 
an integrated card model Intel 915 GM. I continue using the VESA driver 
on the laptop under svgalib 1.9.24.

I have investigated it further. Perhaps it is a bug on the VESA driver 
solved on the 1.9.24 series. On my desktop computer svgalib 1.4.3 uses 
the nVidia NV3 driver and works ok. But if I configure 
/etc/vga/libvga.config for using the VESA driver on the 1.4.3 version, 
linrad crashes on the desktop computer in the same manner as the laptop.

It works perfectly know under svgalib and under X, so we can enjoy it 
until new bugs are introduced on the next version or the hidden bugs 
appear again.

Anyway, thanks very much for Linrad and for your great debugging help

73, Ramiro.
